In a study of fossils spanning 63 million years, University of Illinois animal biology professor Jonathan Marcot and his colleagues found that current patterns of mammal biodiversity in North America are a relatively recent phenomenon. [Credit: Photo by L. Brian Stauffer]
“Latitudinal Diversity Gradient — “latitudinal” meaning how far north or south of the equator, “diversity” meaning the number of species, and “gradient” meaning the transition between high and low. We’ll just call this mouthful the LDG for short. “
It’s pretty obvious that global cooling caused the diversity gradient, but we can’t say that.
Liberals are the part of science right? So... Mammals are all different. BUT, we humans are all exactly the same. There are ZERO genetic differences. Right? Heck, you can even change your gender regardless if you have XX or XY chromosomes.
